IMPROVEMENT lN APPARATUS FOR SUPPLVING OIL TO LAMPS.

Specification forming part of Letters Patent No. 160,653, dated March 9,1875; application filed August 13, 1874.

To all whom it may concern:

Be it known that I, RICHARD V. DE GUINoN, of Jersey City, in the countyof Hudson and State of New Jersey, have invented a certain new andImproved Apparatus for Supplying Oil to Lamps, of which the following isa specification:

This invention consists in the combination of avessel containing airunder pressure with one or more cisterns containing petroleum or otherburning-fluid, and with one or more burners, in such a manner that whenthe comniunieation between the air-chamber and the oil cistern orcisterns, and between the oil-cisterns and the burners, is opened thepressure of the air forces the oil to the burners, which may be situatedatdit't'erent distances from the air-vessel, and a uniform supply of oilto the burners can be effected.

This invention relates to certain improvements in that class ofapparatus in which oil is elevated to a burner-tube from an oil-tank bymeans of compressed air.

This invention is illustrated in the accompanying drawing, whichrepresents a sectional side View.

The letter A in this drawing designates a vessel, which is charged withair under pressure, said vessel being provided with a supplypipe, at,which can be connected to an air-pum p, so that the supply of compressedair can be renewed whenever it may be required, or that a uniformpressure can be maintained in the air-vessel. From said air-vesselextends a pipe, b, which communicates with one or more oil cisterns, B,so that, if said cistern or cisterns are charged with petroleum or otherburningfluid, and the communication between the airvessel and thecistern or cisterns is opened, the liquid in said cistern or cisterns isexposed to a pressure corresponding to the pressure existing in theair-vessel. Said cisterns are provided with supply-pipes 0, throughwhich the burningfluid is introduced, and this fluid discharges throughpipes cl, which extend down nearly to the bottoms of the cisterns, andwhich serve to carry the burning-fluid to the burners G.

If my apparatus is to be used for streetlamps I use a large air-vesselsituated at any convenient place, and connected to an air-pump whichwill be driven by steam-power. Near each lamp-post I place anoil-cistern, as described in my Patent No. 140,815, dated July 15, 1673,and each of these cisterns communicates with the air-vessel and with theburner of the lamp situated next to it. By this arrangement I am enabledto produce a uniform supply of oil to a large number of street-lampsdistributed over an extensive area with little trouble and expense.

The cisterns B can be made large enough to hold a suflicient supply ofoil for several months, so that the lamps can be supplied with oil for along time simply by opening the communications between the cisterns andthe airvessel. As soon as these communications are closed the oil ceasesto flow to the burners, and the flames are extinguished.

My apparatus may, however, be also used for lighting buildings, and inthis case one airvessel and one oil cistern may be used, the cisternbeing made to communicate with all the burners which are to be suppliedwith oil. If the burners are situated at different levels above theoil-cistern the supply of oil to the several burners can be regulated bysuitable stop cocks.

The great advantage of this arrangement is that the oil-cistern can belocated outside the building which is to be lighted, and it may beplaced under ground, so that the risk of fire is reduced to a minimum.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with a street-lamp post having a burner, of one or moreoil-cisterns having discharge-pipes emanating from the oil-space of thesame, and leading to the burner or burners, said cistern or cisternsbeing connected by an airsupply pipe having a stop-cock, said pipeextending from an airchamber for holding compressed air located at asuitable distance from the cistern or cisterns, the compressed air beingreleasable at will from its chamber into the oil cistern or cisterns,and serving to force the liquid oil to the burner or burners,substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of August, 1874.
